Play with colors. See what you've been missing. Chrooma uses real color science, not RGB shortcuts. Extract a palette from any photo and understand immediately why those colors work together: which harmonies are present, where they sit in Munsell space, what temperature balance they create. Or mix your own colors with spectral calculations that model how pigments actually behave. PHOTO ANALYSIS Pull a palette from any photo and understand it immediately: • Unlimited extraction from camera or library • Harmony detection, temperature mapping, balance analysis • Dedicated fullscreen modal with one-tap export • See what Pro analysis unlocks before you buy EXPLORE — 23 Interactive Challenges Put your color vision to the test for real. Sort Munsell value steps, identify simultaneous contrasts, reconstruct palettes from memory. Scoring uses CIEDE2000 perceptual difference. You'll discover where your perception is sharp and where it isn't. COMPOSE — 56 Generative Styles Turn any palette into shareable art. Geometric tiles, flow fields, Voronoi cells, aurora gradients, Albers-style overlays. Export as PNG or animated MP4. EXPLAIN — Color Theory You Can See 10 interactive pages: Itten's 7 contrasts, Munsell notation, Goethe's color theory, 460+ color names with etymology and history, gamut visualization, harmony rules, light physics. Not a textbook. Every concept is something you interact with. MIX — Paint Recipes with Spectral Physics Kubelka-Munk theory models how light scatters through pigment layers. Blue + yellow produces a muted olive, not bright green, because that's what real paint does. Spectral reflectance curves from 24 real pigments (Golden Heavy Body Acrylics, measured with a spectrophotometer). Separate engines for paint, light, and colorant. COLOR COMPARE Pick two colors and see exactly how they relate. Perceptual distance (Ī”E₀₀), WCAG contrast ratio, harmony type, temperature delta, Itten contrasts. MORE • Gradient comparison across 4 color spaces (HSL, Lab, OKLCh, sRGB) • Color of the Day with a new curated color every morning • Weekly palettes tied to seasons and weather • Your Color Imprint, a personality profile that evolves monthly • Palette management with unlimited palettes • Works offline, no account required WHO USES CHROOMA? Painters who want to understand why their mixes don't turn out as expected. Art students studying Itten and Munsell. If you're decorating a room and need to pull a palette from a photo, it does that. And if you just want more than a hex picker, the challenges alone are worth it. PRICING Free to explore. One purchase unlocks everything. No subscription, no ads, ever. PRIVACY No account. Your palettes stay on your device. Optional anonymous analytics, adjustable in Settings.
